MAIL-BAG- DELIVERER.

Specification of Letters Patent.

Patented July 12, 1910.

Application filed April 6, 1910.. Serial No. 553,776.

. useful Improvements in Mail-Bag Deliverefs; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to mail bag deliverers, and is designed as animprovement on my Patent No. 948,217, patented February 1, 1910.

To more fully understand the invention reference is had to theaccompanying drawings', and the particular features of novelty will bemore succinctly pointed out in the claims.

In the drawings in which like characters designate the same parts in theseveral views Fi re 1 is a lon itudinal section through a hollowvertical standard, the operating mechanism of the mail deliverer beingshown in side elevation. Fig. 2 is a flag mentary view showing thelocking dogs positioned with relation to the hollow support. Fig. 8 is asection on the line 3-3 of Fig. 1, and Fig. 4 is a detail perspectiveview of the carrier.

In the present invention I have illustrated a hollow standard or pipe 1,which may be provided with the supporting feet 2, secured to a suitablebase by bolts or otherwise, and it is evident that stay rods 2 may alsobe employed for anchoring the vertical support.

The upper end of the support is slotted, as at 3, and adjacent the slotsare the pivoted locking dogs 4' adapted to swing laterally in a verticalplane.

In the drawings the movable carrier consists of the elongated member 5having a neck portion 6 of a width adapted to fit snugly in the slot 3,and inside of the hollowstandard is a curved plate 7 disposed againstsaid neck and securely atlixed to the elongated member in any suitableway, illustrated in the drawings as comprising the bolts and nuts 8.

On the outside face of the elongated memher, and held in position bytheupper bolt 8, is a bracket or support having an upturned ofisetportion 9 adapted to engage the underneath face of the upper trigger arm10, in order to limit the downward movement of same. The upper triggerarm 10 is suitably pivoted or hinged, as at 11, to the elongated member5, and is provided with a rear extension or arm 12 extending throughsaid slot 3 into the hollow standard and provided with a suspendedweight 13. The lower trigger arm 14 is similarly pivoted or hinged, asat 11, to the elongated member 5, and this lower arm is provided withrearwardly extending otfset strips or fingers 15 adapted to rest on topof the lateral arms of the supporting dogs a and hold the carrier in itsuppermost position when elevated.w These fingers extend from both sidesof the lower trigger arm and straddle the elongated member, as shown inFigs. 3 and 4:. They also slightly diverge, as shown in Fig. 3, toproperly engage the horizontal arms of the do s. I6 designatessuitable,triggers, and in the drawings have simply been illustrated asshown in my former patent as consisting of laterally swinging memberspivoted on the ends of the trigger arms, and having projecting fingersadapted to receive the rings at the top and bottom of the mail sack.

In the present construction the movable carrier is shown as suspended bymeans of a bail 17 secured to the end of the cable 18, reeving over apulley 19 journaled in the upper partof the standard, the cable 18passing out through a suitable opening 20 in said standard. The pulley19 may be journaled in any suitable way, but in the drawings this hasbeen simply illustrated by means of a bifurcated bracket 21 secured bymeans of a nut or rivet 22 to the top of a removable cap 23.

In Fig. 1, the carrier is shown in its uppermost position with the mailbag in position to be delivered, and in Fig. the trigger arms on thecarrier is shown when the mail bag has been delivered and the carrierfalls to its lowermost position, indicatedat a.

In its lowermost position it will be obvious that the carrier may beeasily reached by the operator,with0ut the use of a platform or ladder,and when the mail bag is to be placed into position the trig or arms areswung forwardly toward eac other, the

movement of the upper arm beinglimited by 4. the position of the support9 and the length of the bag being compensated for by the unrestrictedvertical movement of the lower trigger arm. The mail bag being placed inposition on the triggers, as clearly shown in Fig. 1, it will be obviousthat the carrier may be elevated to its uppermost position by slightlyhauling on the cable 18, and by the structure illustrated practicallythe only weight to be elevated is that of the mail bag plus the lightweight of'the carrier.

As the carrier is elevated with the tri ger arms in their set position,when the 0 sets 15, engage beneath the lateral arms of the supportingdogs 4 (with which they are in vertical alinement) the ends of the dogsare swung outwardly, as shown in dotted lines in Fig. 2, so that theoffset fingers 15 ride above the lateral arms of the dogs, when thelatter swing back in place and are in position to support the offsetfingers 15, and hence the carrier. Suitable stops are provided toprevent the lower arms of the dogs from swinging inwardly. These stopsare illustrated in Fig. 2, as at 4, where the pin that forms the stop isbent over and also forms the axis for the swinging dogs.

When the collector arm on the train strikes the bag it will swing thetriggers 16 in a horizontal plane, the bag being delivcred without anystrain on the apparatus, and as soon as the bag is delivered the upperarm will swing upwardly, owing to its counterbalanced weight 13, and thelower arm will swing downwardly, owing to its weight, thus moving thefingers 15 away :t'romthe supporting dogs, allowing the whole carrier todrop into position for inserting a new bag in place.

In Fig. 1 there is also illustrated a counterweight cooperating toassist in elevating the carrier and mail bag, the counterweight being ofa weight slightly less than the weight of the carrier. Any suitable formof counterweight may be employed, and this has been simply illustratedas an oval-shaped lead 18 carried by the flexible member such as a chainor cable 18, and from the position shown in Fig. 1 it will be obviousthat when the mail bag is delivered the weight of the carrier will causeit to fall down to its lowermost position, the weighted lead 18retarding its movement and providing against shocks. The counterweightalso, of course, assists in elevating the carrier and bag.

Having thus described the invention, what I claim is 1. In a mail bagdeliverer, the combination of a hollow upright provided with alongitudinal slot, a movable carrier operat-v ing along said slot, anupper and a lower trigger arm pivotally mounted on said carrier, meansfor detachably securing a mail bag on said trigger arms,-an extension onsaid upper trigger arm disposed within said scape 1 hollow support, aweight suspended on said extension,'means for elevating said carrier,and means for holding said carrier latched in its elevated position,substantially as described.

2. Ina mail bag deliverer, the combination of an upright, a movablecarrier operating along said upright, an upper and-a lower trigger armpivotally mounted on' said carrier, an offset projection engaging saidupper trigger arm to limit its downward movement, means for swingingsaid upper trigger armnpwardly upon being released from its setposition, means for elevating said carrier, and means coiiperating withsaid lower trigger arm for holding said carrier latched 1n 1ts elevatedposition, substantially as described.
